Local Lattice Distortion in High-Entropy Carbide Ceramics

Metals, 2021
Using the ab initio calculations, we study the lattice distortion of HfNbTaTiVC5, HfNbTaTiZrC5 and MoNbTaTiVC5 high-entropy carbide (HEC) ceramics. Results indicate that the Bader atomic radius and charge transfer in HECs is very close to those from ...

Point defects and their effect on dielectric permittivity in strontium titanate ceramics [PDF]

Science of Sintering, 2021
The origin of dielectric properties of strontium titanate ceramics is investigated using DFT calculations in periodic system. It was determined that the main factors contributing to the increase in dielectric permittivity are: tetragonal ...

Mining of lattice distortion, strength, and intrinsic ductility of refractory high entropy alloys

npj Computational Materials, 2023
Severe lattice distortion is a prominent feature of high-entropy alloys (HEAs) considered a reason for many of those alloys’ properties. Nevertheless, accurate characterizations of lattice distortion are still scarce to only cover a tiny fraction of HEA ...

Atomistic mechanism for whole-field distortion of the substitutional solid solutions

Materials & Design, 2022
The exploration of lattice distortion is of great significance to design and improve the substitutional solid solutions (SSSs). However, the distortion caused by substitution atoms is not well understood.

Achieving enhanced toughness of a nanocomposite coating by lattice distortion at the variable metallic oxide interface

Materials & Design, 2022
Ceramic coatings are in general a kind of brittle material because they are predominantly made up of ionic crystals that avoid dislocation motion caused by lattice distortion.

Lattice-Distortion-Induced Change in the Magnetic Properties in Br-Defect Host CsPbBr₃ Perovskite Quantum Dots

, 2023
Herein, we report temperature- and field-induced magnetic states in CsPbBr3 perovskite quantum dots (PQDs) attributed to Br defects. We find that temperature-dependent structural distortion is the main source of various temperature-induced magnetic ...

Accurate lattice parameters from 3D electron diffraction data. I. Optical distortions

IUCrJ, 2022
Determination of lattice parameters from 3D electron diffraction (3D ED) data measured in a transmission electron microscope is hampered by a number of effects that seriously limit the achievable accuracy.

Formation and Effect of Deposited Thin TiO2 Layer With Compressive Strain and Oxygen Vacancies on GaAs (001) Substrate

Frontiers in Materials, 2022
The integration of metal oxides and GaAs semiconductors is quite attractive for its potential applications, but interfacial diffusion and lattice mismatch usually cause huge challenges toward achieving high-performance electronic devices. In this article,
